SPECIFICATION forming part of Letters Patent No. 660,245, ated October23, 19 00.

Application filed July 26, 1900. Serial No. 24,915. (No model.) I

To all whom it may concern:

Be it known that we, JOHN BUNTE and WILLIAM SORIMGEOUR, Jr. residing atPortsmouth, in the county of Norfolk and State of Virginia, haveinvented certain new and useful Improvements in Hose- Clamps, of whichthe following is a specification, reference being had therein to theaccompanying drawings.

This invention relates to tube-clamps especially intended to clampflexible pipes, such as hose-pipe, to nozzles, rigid links, or otherrigid connections.

The object of the invention is to make a simple and adjustable metallicclamp for the purpose described having features of novelty hereinafterclaimed.

Figure 1 is a broken perspective view of a hose clamped to a nozzle bytwo of the clamps of this invention. Fig. 2 is a side elevation, andFigs. 3 and 4 end elevations, in reverse position of the clamp. Fig. 5is an end view of clamp-strap and nut. Fig. 6 is a section of the nut.Figs. 7 and 8 are elevations of modifications of the clamp.

A indicates a flexible hose of any ordinary construction, and B ametallic nozzle or pipe to which the-hose is attached.

O is the metallic band, constituting the body of the improved clamp.This band may be of iron, steel, copper, or other metal which issufficiently flexible to bend around the,

hose. The band is preferably flat, as shown, but may depart somewhatfrom such form. The ends 0 O of such band are rounded and asegment of ascrew-thread cut on the rounded face. The ends may taper, as shown inFigs. 1 and 8. The thread is on theouter face of the band when the sameis coiled into a loop.

D indicates a nut of usualconstruction, except that the bore is tapered.The thread on the nut should be of the same pitch as on the ends 0 ofthe strap.

E is the inner bushing 0f the clamp. This is a curved piece of metalforming about an arc of the surface of the hose. The bushing E may berigid, but is preferably slightly yielding. The bushing E may be held tothe strap 0 by widening one end of the bushing,

perforating the widened portion, and passing the strap 0 through suchperforation; or the bushing may be otherwise connected, so as to bereasonably secure in its relation to the band C.

The band C is looped around the hose, the ends extending to one sidethereof, as shown in Fig. 1. The bushing E extends across the spacewhere the outwardly-turned ends 0 of the band have an opening between.Now by applying the nut and turning the same to clamp the band a mostpowerful pressure may be applied. The tapered form of the nut preventsthe cramping of the band in such manner as to make a sharp angle, sothat there is little danger of breaking the band. The ends of the bandtend to spring outwardly, so as to give good engagement with the nut andcause the same to move on the threaded ends of the band much the same asa nut would move on a solid screw-bolt.

Figs. 7 and 8 show modifications wherein the band is made up of sections0 or 0 each being less than the length needful to surround the hose, butin other respects like the band heretofore described. The mode ofapplication is apparent. Bushing -pieces E span each break in the clamp.

The bushings may be shorter where three are used, as in Fig. 8, butshould be long enough to span the gap in the clamp.

We claim 1. A hose-clamp consisting of a metallic band havingscrew-segments on its end portions, a nut engaging such end portions,and a bushing extending across the opening below the nut.

A hose-clamp consisting essentially of a metallic band with threaded endportions, a bushing having a hole through which one end of the bandpasses, and a nut with tapered thread engaging thethreaded ends of thehand, all substantially as described.

In testimony whereof we aflix our signatures in presence of twowitnesses.
